There are cases where you can give the EXACT SAME script/character arc/iconography/etc. to a white performer and to a performer of color, and the overall effect WILL BE DIFFERENT. Race is real. People respond to it, often on levels they aren't entirely aware of. So it actually misses the whole entire point of discussing race and racism if your sole defense is "but we're just treating them the exact same way we treat white characters!" It may be true, or it may not be true, but either way it's singularly useless.Some fans seem to find gender easier to understand than race, so think of it this way: if there's a character that isn't very bright but always uses sexuality to manipulate other people, does it make a difference if that character is a man or a woman? Isn't it more of a stereotype in one case than in the other? And if some writer or producer said, "Oh, it's not sexist -- this is just what we were going to do, and we thought we might hire a male actor, but we went with a woman instead, so we kept the same stuff!" that doesn't magically make her not a sexist cliche, does it? If they'd cast a man, the character would read one way; when they do cast a woman, it reads differently. Same character. Different, because of the baggage we bring surrounding gender.
